SATELLITE ANALYSIS AND TRENDS...BIG PICTURE FROM WATER VAPOR AND IR
SHOWED MAIN UPPER LOW THAT HAS DEEPENED OVER THE PAST 24HRS NOW CENTERED
ABOUT 350 MILES WEST OF KSFO.  ONE JET WITH MAX SATELLITE WINDS OF 80KTS
WAS ROUNDING THE TROUGH AND CENTERED AT 33N/130W AND PROBABLY PARTLY
RESPONSIBLE FOR LOW'S DEEPENING PAST 24HRS.  THIS IS THE JET THAT SHOULD
PUSH FRONTAL BAND INLAND...BUT NOT BEFORE A TEASE THIS MORNING AS FRONTAL
BAND WAITING FOR WAVES ALONG IT TO NUDGE IT INLAND.   AND LATEST MICROWAVE
PASSES FROM NOAA AMSU...NASA TRMM AND AMSR-E SHOW THAT EVEN THOUGH THE
FRONTAL BAND IS ONLY 1-2 DEGREES WIDE IT HAS AVG INSTANTANEOUS RAIN RATES
OF OF UP TO 0.15"/HR WITH MAX RATES TO NEAR 0.3"/HR SPRINKLED ALONG THE
SOUTH AND DEFORMATION PART OF THE BAROCLINIC BAND OFFSHORE.   MAX PWS
FROM AMSU WERE NEAR 0.91" WITH FRONTAL BAND...BUT COMBINED WITH GREAT
DYNAMICS AND GOOD MOISTURE TRANSPORT...ONLY THING STOPPING IT FROM BEING
A GOOD SOAKER FROM SFO BAY AREA SOUTH THRU MONTEREY COUNTY IS AFFECTS
OF SHORT WAVE EMBEDDED IN BAND AND JET THAT COULD POSSIBLY SLOW OR TRY
TO PULL BAND WEST A BIT.  SHORT TERM FORECAST NAM MODEL COMING IN SHOWS
A PROGRESSIVE BAND...BUT WILL BE TRICKY AS TO TIMING THAT BAND INLAND.
AND IT IS THE DYNAMICS THAT HAVE HELPED CONTINUE TO GENERATE THE HIGHER
PW VALUES WITH FRONTAL BAND AS PER 2.5 DAY PW LOOP OFFSHORE.
AND THEN THERE IS SECOND STRONGER JET WITH SATELLITE WINDS MAXING OUT
AT 140KTS CENTERED AT 42N/139W WOULD HELP SET UP SYSTEM FOR LATER IN
THE WEEKEND...POSSIBLY FURTHER SOUTH.
WILL CONTINUE TO MONITOR...SEE GRAPHICAL PRODUCT ON INTERNET IN 10
